I am new to this website. I have done a project on Linux device Drivers i.e. serial port Communication Through RS232 protocol . In my project it is able to write the that to other system through Null Modem But it is not able to read the data from the system . can anyone help me by providing the solution for this question

Welcome to electronicspoint.

You need to supply more information:

• What is the "other system"?
• Do you get any data (perhaps garbled) or no data at all?
• What debug possibilities do you have?
